Product Overview

Yinuo New Material Technology (Heze) Co., Ltd. presents a high-performance powder-type anti-tack agent specifically formulated for uncured and compounded rubber sheets. This product is designed to prevent unvulcanized rubber compounds from sticking together during handling, stacking, and storage-. Formulated with a proprietary blend of inorganic fillers, active surfactants, and rubber-affinity functional groups, our anti-tack agent forms a uniform, elastic coating on the rubber surface that effectively separates sheets without compromising subsequent processing.

The powder is easily dispersed in water to create a stable suspension, which can be applied via dipping or spraying in batch-off lines. Upon drying, it leaves a thin, flexible barrier film that prevents adhesion, dust contamination, and surface defects – ensuring smooth handling and storage of rubber compounds.

Key Features & Benefits

Superior Anti-Tack & Release Performance
Our powder anti-tack agent provides excellent anti-blocking and release properties for most types of rubber, regardless of viscosity or tackiness-. It effectively prevents unvulcanized and compounded rubber sheets from sticking together during storage-, ensuring clean separation and easy handling throughout the production process.

Uniform, Flexible Protective Film
When applied, the anti-tack agent forms a soft, elastic coating layer on the rubber sheet surface. This film flexes with the rubber during expansion and contraction, maintaining its protective integrity without cracking or peeling. It also prevents dust and contaminants from adhering to the rubber surface, avoiding complications in subsequent processing steps.

Excellent Wetting & Substrate Compatibility
Our formulation demonstrates optimum wetting properties on both soft and tacky rubber compounds-. The active rubber-affinity functional groups ensure strong adsorption onto the rubber surface, providing reliable coverage and consistent anti-tack performance across a wide range of rubber types, including natural rubber, synthetic rubber, and various elastomer blends.

No Interference with Curing or Physical Properties
The anti-tack agent does not affect the vulcanization process or the flow characteristics of the rubber compound during processing. It readily integrates into the rubber matrix during curing without compromising the physical and mechanical properties of the finished product. This ensures that the final rubber components maintain their intended performance specifications.

Minimal Equipment Build-Up & Easy Cleaning
Our anti-tack agent leaves only minimal, soft deposits on equipment surfaces, which are easily removable. This reduces maintenance downtime and extends the service life of processing machinery. The dispersion is also low-foaming, preventing operational issues during application.

Stable Dispersion & Easy Handling
The powder disperses readily in water with simple stirring, forming a stable suspension that remains uniform even after extended periods. Should sedimentation occur after prolonged standing (e.g., over weekends or holidays), the soft, voluminous sediment can be easily re-dispersed with minimal agitation. The powder form also ensures superior efficiency and convenient storage and transportation.

Environmentally Conscious Formulation
Developed in accordance with modern economic and ecological requirements, our anti-tack agent contains no hazardous substances and is formulated to be environmentally responsible. Its water-based dispersion system minimizes VOC emissions, creating a safer, cleaner working environment for operators.

Applications

Our powder anti-tack agent is widely used in the rubber manufacturing industry for:

• Tire Manufacturing: Anti-tack treatment for rubber sheets during the mixing and calendering processes

• Rubber Goods Production: Batch-off lines for uncured rubber sheets, strips, and profiles

• Conveyor Belt & Hose Manufacturing: Preventing adhesion of rubber plies during storage and assembly

• General Rubber Processing: Treatment of compounded rubber sheets prior to extrusion, calendering, and molding operations

The product is suitable for use in both spraying and dipping application systems and is compatible with most standard batch-off equipment.

Usage Instructions

1. Preparation: Ensure the rubber sheets are clean and free from excessive surface moisture or contaminants.

2. Dispersion: Add the powder anti-tack agent to clean water with gentle stirring. The powder disperses readily without the need for high-shear mixing.

3. Concentration: Recommended dispersion concentration is typically 2–6% by weight-. For most applications, a concentration of 3–4% is preferred-. Adjust concentration based on rubber type, ambient temperature, and degree of tackiness – higher concentrations are recommended for sticky compounds and summer conditions.

4. Application: Apply the dispersion uniformly to the rubber sheet surface using spray systems or dipping tanks in batch-off lines.

5. Drying: Allow the applied film to dry completely before stacking or storing the rubber sheets. The film forms a fast-drying coating with excellent release properties.

6. Storage: Store the powder in a tightly sealed container in a cool, dry place, protected from direct sunlight. Recommended shelf life: 6 months.
